  • Patent number: 6723344
    Abstract: Matrices that support cell adhesion and growth are disclosed that deliver low heparin-binding affinity growth factor protein peptides in a controlled manner. These matrices comprise covalently or non-covalently bound heparin or heparin-like polymers, which serve to sequester the low heparin-binding affinity growth factor protein peptides within the matrix. The controlled release of some low heparin-binding affinity growth factor or peptides thereof occurs by degradation of some matrix component or dissociation of the low heparin-binding affinity growth factor protein peptides from the bound heparin. This differs from many controlled delivery devices in that release is not controlled solely by diffusion, and the rate of release may therefore be regulated by altering the rate of degradation of the matrix component or the amount of heparin bound within the matrix. The controlled release of such low heparin-binding affinity growth factor proteins such as NGF-&bgr;, NT-3 and BDNF, is demonstrated.

  • Patent number: 6447764
    Abstract: The invention relates to a method for isolating anionic organic substances from aqueous systems using polymer nanoparticles with cationic pH-sensitive surface groups. Extraction can be carried out directly from diluted solutions, biological media (blood plasma, serum, urine, etc.) and complex buffer systems (e.g. PCR preparations contain detergents) without prior derivatization of the samples or addition of binding buffers. After separation from the surrounding medium the conjugates of the corresponding substances and polymer nanoparticles obtained in this manner can be purified through additional washing steps and effectively desalinated. Owing to the pH-sensitivity of the basic surface groups, the bound substances can be released in a targeted manner after separation by modification of the pH of the medium. By using volatile bases contamination of the released samples with ionic residues can be avoided.

    Abstract: A method to assess hypertension by measuring the amount of free and conjugated hydroxyeicosatrienoic acids (DHETS) and metabolites of DHETs, which are metabolites of arachidonic acid (AA) epoxygenases and epoxide hydrolases, in a biological sample which contains the DHETs (using any methods including GC/MS or ELISA) is disclosed. The method further included determining the amount of molecules containing a DHET-specific epitope immunoreactive with antibodies produced against DHETs present in the sample. This amount is compared with a control sample(s). Hypertension is determined through the comparison wherein the amount of increase of free and conjugated DHETs and metabolites of DHETs in the sample isolated from an organism. The present invention also provides a method to assess catalytic activity of AA epoxygenases using immunoassays by measuring the amounts of NADPH-independent epoxyeicosatrienoic acids (EETs) and total (NADPH-dependent+independent) EETs.

  • Publication number: 20020114774
    Abstract: A method for treating pathogenic toxins in a mammal, such as a human, comprising treating the mammal with a therapeutically effective amount of a polymer comprising a cationic group attached to the polymer backbone. The polymer can be a homopolymer or a copolymer. In one embodiment, the polymer is a copolymer comprising a monomer having a pendant ammonium group and a hydrophobic monomer.

  • Patent number: 6361768
    Abstract: A novel hydrophilic ampholytic polymer synthesized by reacting polymerizable amino and carboxy functional ethylenically unsaturated monomers, together with a non-ionic hydrophilic monomer, to provide a polymer having a glass transition temperature (Tg) above about 50° C., and optionally hydrophobic monomer(s), and cross-linking monomer(s). The copolymer is precipitated from a polymerization media which includes a suitable organic solvent. The resulting copolymer is in the form of a fine powder, with submicron particle size. As such it is suitable for use as a thickener or rheology modifier in personal care formulations, such as shampoo, conditioner, and the like, as a bioadhesive, and for other pharmaceutical applications.

  • Patent number: 6342212
    Abstract: Broadly defined adhesive latex formula s exhibiting antimicrobial properties. Such formulations comprise certain antimicrobial compounds, such as, preferably, metal-containing ion-exchange and/or zeolite compounds, are provided. The inventive latex formulations must also exhibit substantially uniform characteristics (such a similar viscosity and/or appearance throughout) in order to provide a functionally and aestheticially pleasing formulation for utilization within any number of applications. In order to provide such an inventive latex formulation, it has been found that compounding of all the base ingredients (polymer, antimicrobial agent, fillers) must be undertaken prior to the final thickening step, which ultimately produces the desired latex. The specific method of producing such formulations is also encompassed within this invention.

  • Publication number: 20010041171
    Abstract: The present invention relates to a method of inhibiting a toxin in an animal, such as a human, by administering to the animal a therapeutically effective amount of a polymer having a plurality of pendant acid functional groups which are directly attached to the polymer backbone or attached to the polymer backbone by a spacer group. The spacer group can have a length in the range from 0 to about 20 atoms. The toxin is, typically, an exotoxin secreted by a pathogenic microorganism, such as a bacterium.

  • Patent number: 6306384
    Abstract: The present invention relates to a method for preventing or treating skin damage which comprises applying to the skin a composition containing an effective amount of a cosmetically or pharmaceutically acceptable compound capable of acting as an electron donor, simultaneously or substantially simultaneously with the application of a composition containing an effective amount of a cosmetically or pharmaceutically acceptable compound capable of acting as an electron acceptor, whereby an exchange of electrons between the electron donor and electron acceptor results in generation of an electrical current on the skin.

  • Patent number: 6280717
    Abstract: A cation exchange resin preparation in the dosage form of dry syrups and the like which comprises a cation exchange resin such as polystyrene calcium sulfonate and a gelleing agent such as carboxymethylcellulose sodium (CMC-Na), and may further comprises a binder such as hydroxypropyl cellulose (HPC). The preparation gelates and/or swells without disintegration for a few tens seconds to a minute or so when taken as suspensions in water or the preparation, per se. Therefore, the sandy feel in the mouth and throat, which is a problem in taking the preparation comprising a cation exchange resin alone, is reduced and the taste and easiness in oral administration are both improved.
